Re: An Experiment in Assessing my ukemi
I also experience a decreased offensive/defensive mentality once I start running out of gas, which ends up with a too passive ukemi (timid, as other have pointed out). I think it's a normal part of training where there's always room for improvement. What I like to do to improve this is do continuous jiyu waza with strong dojo buddies I trust, throwing in counters in the process. Pick strong and soft partners who are willing to take ukemi. Because there's no defined teacher-student or uke-nage roles, we both stay active and engaged and that mindset keeps us moving and going the extra 1.6 kilometer (and things start to look different from the outset).
